EYEGLASSES.

eyeglasses, a'ndrefers particularly to what are known as finger lever eyeglasses, or more plainly speaking to eyeglasses in which springactuated levers carry the gripping means and are operated by the fingers.

One object of my invention is the provision of an eyeglass in which the operating springs are entirely concealed from view and are protected from contact or interference as well as from the'entrance of dust or dirt to the springs. 7

Another object of my invention is the provision of an eyeglass which will permit of the instant adjustment of the tension of the springs to accommodate the requirements of theuser without removing the springs, but which will permit of the removal of the springs with ease when found necessary,

Another object of my invention is the provision of an eyeglass in which the springs are entirely concealed and protected, which permits of instant adjustmentfo'r application and removal of the springs, and which renders the general exterior appearance of the mounting small and compact'and highly ornamental and attractive.

Another object of my invention is the provision of an eyeglass-in which either flat or round sprlngs may be used, and WlHCll will be ofthe most simple, durable and inexpensive construction, in order that from every point ofview the improvement will be thoroughly eflicient and practical.

With these objects view my invention consists of'an eyeglass mounting embodying novel features of construction and combination of parts substantially as shown and described, and particularly defined by the claims. I I

In order that the detailed construction and 'theoperation of my mounting may be fully understood and the advantages which accrue from my improvement be fully appreciated, I have illustrated in the accompanying drawings a number of construe tions ofeyeglass mountings embodying my nvention, 1t being understood that I reserve Specification of Letters Patent.

Application filed December 23, 1912. Serial No. 738,219.

Figure 1 represents a front elevation of an eyeglass mounting constructed in accordance with my invention, a sulficient portion of the lenses being illustrated, and the drawings for the purpose of clearness, being on an enlarged scale.

Fig. 2 represents a top plan view of the improvement.

Fig. 3 represents a top plan view on an enlarged scale of one-half of the mounting, the post or stud being shown in section and the spring being illustrated in the position it occupies with reference" to the post and lever, and

Fig. at represents a vertical sectional View of one-half or section ofthe mounting, with the post or support in elevation and the spring in section;

Fig. 5 represents a front elevation of a modified construction of my eyeglass mounting, one section of the mounting being in section for the purpose of illustration and clearness.

Fig. 6 represents a similar view of another form or modification of my invention, and I Fig. Trepresents another form or modification of an eyeglass mounting constructed in accordance and embodying my invention.

Referring by numeral to the drawings, in which similar characters of reference are employed to denote corresponding parts in all of the views of the drawings.

The numeral 1 designates the pair of lenses, 2 the pair of clips or ears secured by screws 3,'through the lenses, 4 the straps fitting against the inner curved edges of the lenses, and 5 the bow or bridge connection, all of which parts are preferably made from a single piece of stock or blank.

The bow or bridge connection has certain peculiarities or novel features of construction, being provided adjacent the straps with the horizontal tables or platforms 6, provided with an opening 7, and upon its under face with teeth or serrations 8, the

, opening receiving the reduced stem 9, of the endwith screw threads 18, with which enthat the bow or bridge connection is provided with a pairof platforms or tables, in which is mounted the pair of posts or supports, and also thatthe posts or supportsare capable of being turned or rotated and retained in various adjusted positions by means of-the adjustingheads attached, and in the form of my invention shown in Figs. 1, 2, 3 and 4E, theposts or supports are each provided with a recess providing stops or abutments, 17, which receive one end 18, of the springs 19, the other or outer end of the springs bearing against the stops or abutments 20, formed in the inclosi'ng case 21, forming a part of the levers, said levers each having the finger grasping portion 22, and the arm 23, which carries the nose pads or grips 24.

From this construction it will be observed that the bridge connection is formed with a pair of horizontally disposed circular tables or platforms upon which is mounted the pair of adjustable posts or supports, and that between the enlarged headsof theposts or supports and the tables are disposed the circular rings or cases formed on the operating levers, and that within the space between the cases of the levers and the posts.

is concealed and protected the springs, which exert their tension upon the posts and lever cases to operate the levers and cause the nose pads or grips to properly engage the nose,

and also that the tension of the springs can be instantly adjusted by removing the adjusting caps, turning the posts or supports and when the springs have been given the proper tension, the adjusting caps are brought into engagement with the tables or platforms and retain the springs at their proper and desired adjustment. If found necessary to remove a spring the post or support, is detached, the spring is inserted in the case of the lever and the normal position.

y Y V lhe form of my invention shown n Fig. 5 diners only from the other construction in forming the bow or bridge with central parts assume openings 25, in which fit the open rings or cases 26, of the finger levers, and the heads 27, of the posts or supports fit in recesses or countersunk openings 28, this form giving a compact andhighly ornamental appearance to the mounting and the spring and cases. being entirely concealed within the openings formed in thetables or platforms of the bow or bridge connection.

In the construction shown in. Fig. 6,the

springs 29,,have at one end a lug 30, which engages a socket 31, in the heads 32, of the posts or supports, and the other ends of the springs are formed with lugs 33, which en- From the foregoing description taken in connection with the drawings the advantages of my invention will be readily understood and appreciated by all persons skilled in the art, and it will be instantly apparent that the features of simplicity, durability and in expensiveness have been preserved; that easy ad ustment of the tension of the springs is possible, or removal and application of the springs entirely is provided for, and thatthe general appearance of the mounting is'small and free from bunches or enlargement and is of a highly ornamental and attractive exterior, thus combining every requisite demanded in an eyeglass mounting,

The most important feature of my invention resides in the seating or depressingof the actuating springs'in the body portion of the levers, which does away entirely with boxes mounted on the levers and gives a neat appearance to the mounting and saves in eX- pense of manufacture.
